Question

What is a dipole-dipole force?

• A. The force that acts between the different polar ends of molecules
• B. The force that acts within the same polar ends of molecules
• C. The attractive force that occurs between an ion and a dipole
• D. The force that acts between non polar molecules

Answer 1

The correct option is A The force that acts between the different polar ends of molecules

A dipole-dipole force is a force that acts between the different polar ends of molecules.

There is a dipole-dipole force between chlorine and hydrogen between two different polar ends of molecules. The relatively positive end of a polar molecule will attract the relatively negative end of another HCl molecule.

Therefore, option A is correct.
